1环境配置

因为之前用过vs2017环境是已经配置好了的，所以在这里就不再一一赘述

首先选择创建一个c++的控制台应用程序并且修改地址

然后在源文件里面创建一个c++的解决方案

接着就可以着手于代码的编写

然后从作业给出的链接中下载git并进行安装

2代码设计思路

看了一下提前交的大佬的作业，用的java和Python，我表示给大佬献上膝盖，辣鸡如我所以只能选择用正在学的c++进行编写，所以我用了两个半小时用循环语句和条件判断语句写出了基本符合题目要求的代码，并且相除不会出现分数

代码总共240行左右，耗时两个半，写出了基本符合要求的代码下面贴上运行截图

如图，输入20后会自动随机生成20道四则运算题目，并且在除法中不会出现非整数

3记录你使用github克隆项目以及提交代码的整个过程

在克隆项目的时候发现没有设置好拷贝路径导致克隆下来的文件无法找到，经过修改相关路径后克隆成功并且在自己的指定路径中出现了相同的文件

下面为提交代码过程

首先在拷贝下来的文件夹中创建一个以自己github名字命名的文件夹然后再用vs2017在里面创建一个新的c++控制台项目

接下来将自己写好的代码保存到该项目中

然后打开事先下载好并且安装了的git

首先输入git add .（注意这里的.与add中间有一个空格）

然后输入git commit -m"吕涛的第二次提交"（提交了第一次不合适后修改了）其中""放的是这次提交的名称

然后输入git status指令当出现nothing to commit, working tree clean的提示语句后即表示可以进行push并且提交到你的源代码仓库中了接下来输入git push origin指令

会出现如图所示的代码表示已经上传成功到你的代码仓库了接下来打开自己的仓库即可看到相应的代码提交
